Limelight Networks Sets New Content Delivery Traffic Record

Company Release - 1/4/2018 3:55 PM ET

Surpasses previous online traffic record set in November 2017 by more
than 20 percent

TEMPE, Ariz.--(BUSINESS WIRE)--
Limelight Networks, Inc. (Nasdaq: LLNW),
a global leader in digital content delivery, today announced that it
delivered record online traffic levels in December 2017, a 21 percent
increase over its previous record set in November 2017 and a 23percent
increase from December 2016. Record traffic volume was driven by several
large customers choosing Limelight to meet the high demand for content
during their busy and performance-sensitive holiday season. This was in
addition to regular day-to-day traffic sent over the Limelight content
delivery network (CDN).

Despite the record demand, Limelight’s focus on service quality resulted
in an historic low number of trouble tickets. In addition, with
system-wide software and infrastructure upgrades, Limelight servers are
delivering record traffic per server. Compared to December last year,
Limelight delivered over 20 percent more traffic, using 5 percent fewer
servers and the higher service quality resulted in almost 50 percent
fewer customer incidents.

“We’re very pleased with the multidimensional improvements in our
performance, functionality and efficiency. Those improvements were the
underpinning of our success in efficiently serving record-breaking
traffic,” said Dan Carney, Senior Vice President of Operations at
Limelight. “Given our global reach, connectivity, secure and private
interconnection, and connectivity to last mile providers, we’re more
than a Content Delivery Network. Our capabilities are introducing us to
new opportunities in the edge computing space. We look forward to
continuing to serve our customers who trust Limelight to solve
increasingly challenging business problems.”
